All of the above
Potential drawbacks to sidemount include (choose all that apply)

_________ cylinders require you to wear more weight, all else being the same.
Steel
Enriched air nitrox
Aluminum
DIN valve
Aluminum
If you’re using a dry suit, you would most likely supply it from your _________ regulator.
right
left
Right
Under what circumstances as a recreational sidemount diver might you use a weight belt with your crotch strap over it?
-Under no circumstances.
-When you have ample quick release weight in another system.
-When you have no choice.
-When you have ample quick release weight in another system.
The most useful place to attach accessories you will use a lot in sidemount is usually the _________ area.
-rear/buttocks
-upper chest
-front waist
-lower leg/ankle
-rear/buttocks
The usual procedure when kitting up in sidemount is to first put on both cylinders, then connect the low-pressure inflator and open the valves.
True or False
False
The most common entry technique in sidemount diving is to put on your cylinders
- in the water.
- before a giant stride.
-before a seated back roll
in the water
Wearing all your kit including two cylinders at reserve pressure, with an empty BCD and holding a normal breath, you find you float at about eye level. This means
.
- Your weight should be about right.
- You need to remove some weight.
- You need to add some weight.
Weight should be about right
During a dive in two-cylinder sidemount, you switch cylinders periodically. One reason you do this is
- to prevent the regulators from clogging.
- so your buddy knows both systems work.
- to keep both cylinders relatively close in buoyancy.
- to keep both cylinders relatively close in buoyancy.
While neutrally buoyant and hovering, you find that your natural position in the water is with your feet low on a 45 angle. This means you should
Correct
- shift weight toward your feet so you are vertical.
-shift weight toward your head so you are horizontal.
-do nothing and maintain this trim position.
-shift weight toward your head so you are horizontal.
The ____________ kick is popular because, among other reasons, it doesn’t stir up the bottom.
Frog
During a dive, after using about a third of the gas in each, you notice that your aluminum cylinders seem to be rising too high at the rear. To remedy this, you may
- remove and hand carry them.
-breathe only from one cylinder.
-resecure them to a lower attachment point.
-resecure them to a lower attachment point.
The most common exit method in sidemount is to
-remove both cylinders, then exit.
-remove one cylinder, then exit.
-remove no cylinders, then exit.
-remove both cylinders, then exit.
While diving in two-cylinder sidemount, the regulator on your right cylinder suddenly fails in a runaway freeflow. After shutting the valve, your first response would be to
- breathe from your left cylinder.
-get gas from buddy.
- breathe from your left cylinder
While diving in sidemount, you’re breathing from the long-hose second stage. Your buddy signals “share air.” You will give your buddy
-the short-hose second stage you’re not using.
-the long-hose second stage from which you’re breathing.
-the long-hose second stage from which you’re breathing.
Which of the following are benefits of sidemount? (Choose all that apply.)
-Ease of streamlining equipment. undefined
-Ease of streamlining equipment
-Easier equipment transport. undefined
-Easier equipment transport
-Increased gas supply. undefined
-Increased gas supply
-Accessibility
-Adjustability
-Problem Solving
All of the above
In two-cylinder sidemount, one drawback is more complex
-buddy team dynamics.
-dive planning.
-gas management.
Gas mangement
In sidemount, for gas sharing you usually have a hose that
-is standard length.
-is 1.5-2 metres/5-7 feet long.
-attaches to the second stage left side.
-is 1.5-2 metres/5-7 feet long.
In sidemount diving, it is common to use more than one system to distribute weights, including putting weights on cylinders in some cases.
True or False
True
In recreational sidemount, it is typical to wear a snorkel throughout the dive, just as you do in backmount recreational diving.
True or False
False
When diving in two-cylinder sidemount, the procedure is to breathe from one cylinder until you reach reserve pressure, then switch to the other cylinder.
True or False
False
During a dive wearing two-cylinder sidemount, one of your regulators starts to freeflow. Your first response to this would be to
-switch to the other cylinder.
-share gas with my buddy.
-breathe from the freeflowing regulator.
-switch to the other cylinder.
During your training dives, your instructor has you release the tail of your cylinder and then extend it in front of you with the top still secured to your harness, and swim. You learn to do this because
- it’s a useful defense posture against predators.
-it’s a way to prepare for removing a cylinder at the surface or as you exit.
-many divers prefer to conduct the entire dive this way.
-it’s a way to prepare for removing a cylinder at the surface or as you exit.
Due to unexpected difficulties, you run out of gas and must share gas with your buddy. Surface conditions make it desirable to swim back to the mooring line before ascending, and your buddy has ample gas to do so. You decide to swim with one leading and one following, so
- you should be in front and your buddy should follow..
- your buddy should be in front and you should follow.
- you should be in front and your buddy should follow..
